The vibrator's steady hum fills the air as Fioterra's sister spreads her legs wider, inviting her brother's kinky touch. He traces the toy along her wet pussy lips, making her shiver. Her breath catches as he pushes it inside, fucking her slowly at first, then picking up the pace. She moans loudly, her body bucking as he expertly teases her clit with his other hand. The vibrator buzzes against her g-spot, making her cry out in pleasure. She's so close, her body tensing, ready to explode in a wave of taboo ecstasy.
